Why use the Tree Jack

  • Saves time and $$$ by separating and removing wellhead components without the use of work over rig.

  • Reduces rig up time.

  • Reduces shock load on cranes while attempting to separate tree from wellhead.

  • Safe System – Minimizes exposure of personnel to typical hazards associated with removing wellhead components.

  • Verifies that tubing hanger is free & tubing has been properly cut.

How it works

  • Hydraulic forces pushing against back pressure valve

    threads separating wellhead flanges or tree valves with

    forces up to 160,000 lbs.

  • Tree Jack assembly is installed onto the threads of the

    tree cap.

  • Separation can take place at any vertical run flange of

    the tree assembly.

  • Separation is not limited at the tubing spool and the

    tubing head adapter.

How it works

  • Determine Tree Jack pusher rod length by measuring

    from back pressure valve threads to approximately two

    thirds to three quarters of Tree Jack window.

  • Install push rod into back pressure valve threads.

  • Install Tree Jack over push rod and secure to tree cap

    threads.

  • Apply pressure to the upper hydraulic connection

    generating up to 160,000 lbs. of separation force.

  • Once tree is separated, dismantle Tree Jack and

    remove tree from well.
